Specification of Letters Patent.

7 Application filed June 10, 1916. Serial No. 102,822.

of the United States, residing at Milwaukee,

county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in OlamlpingVises, of which the following is a specification.

The object of my invention is to provide means for avoiding all machlne work in the manufacture of an ordinary vise, except the screw cutting operation, whereby I am enabled to produce a simple and inexpensive form of vise'which can be sold considerably below the price heretofore prevailing.

In a'companion application bearing even date herewith, a method is illustrated and described whereby ordinary C clamps may be formed by casting upon a steel screw, a swivel head, a thumb nut, and a clamping oke. This invention contemplates the provision of means whereby a vise, adapted to be secured to an ordinary work bench, may be constructed in a somewhat similar manner by casting the jaws of the vise upon a steel screw and upon one or more steel. guide rods in such a relation that the screw may be employed for actuating one of the jaws along the guide rod. Y

, In the drawings- Figure 1 is a plan view of my lmprovcd vise as it appears in the mold after the flask has been removed, except that portions of the casting are shown in section to expose the screw bars and guide rods.

Fig. 2 is fragmentary View of the swivel end portions of the jaw actuating screw, showing also a fragment of the stationary jaw in vertical section, together with a modilied form of operating lever.

Fig. 3 is a view, partly in vertical sec tion, of the movable jaw, showing a modified form of construction.

Like parts are identified by the same reference characters throughout both views.

A j aw actuating screw bar A has a screw thread a formed on one end portion thereof. The other end portion is cylindrical but is provided with an annular channel at an intermediate point which forms a neck a. The extremity of this portion is preferably flattened to form a wing a. This, jaw actuating screw bar A may be placedin a mold with one or more parallel smooth surfaced rods B and C, which are suitably spaced from the screw bar A and extend from the vicinity of the neck a substantially to the threaded end of the screw bar;

Another screw D is also preferably placed in the mold and in a position at right angles to the screw A, and the rods l8 and C are sufiiciently distant therefrom to serve as a bench clamp screw. The mold will, of course, be provided with a cavity or cavities to receive the molten metal from which the cast metal portions of the vise are to be formed, as hereinafter explained. i A set of jaws E and F are then cast upon the screw actuating bar A and upon the rod or rods in such amanner that the jaw E will have embedded therein the neck portion a and parts of the screw bar A adjacent thereto, together with the adjacent ends of the rods B and C. The pattern for the jaw E is preferably formed with a portion corresponding to arm E which partially embraces the rod B and supports the latter throughout a considerable portion of its length. The pattern for the jaw F is so formed that this jaw will have an intermediate portion of the rod C embedded therein, also an intermediate portioirof the screw. threaded part of the screw bar A, whilethe Patented Jlully mm.

lower portion of thej aw F will embrace the upper portion of the rod B opposite. the free end portion of the arm E. The clamping faces 6 andf of the jaws E and F may be formed of cast metal, or, if desired, these posing the lower surface ofthe arm E..

The operating thumb nut J may be cast upon the lower end of the screw D and'an operating lever K is preferably cast npon the wing a". The jaws E and ll, thumb nut J and lever K are cast by first assembling the screws in the mold in connection with suitable pattern members which are I subsequently removed to form the mold cavity into which the molten metal may be poured in order to form the cast metal portions above described. The screws maybe used as a part of the pattern or pattern screws maybe used and replaced by the screws A and D preparatory to pouring the molten metal. The portions of the screws or screw bars, which are to rotate within the cast metal a're'preferabl coated with molding shellac or equivalent material to prevent adhesion or fusion with the molten metal. The guide rods ,7 may be similarly coated. The'molten metal will, of course, flow into the channel around the neck a and into the spaces between the screw threads, thereby formingifemale cast metal screw threads in themembers and H, and also forming an annular swivel flange L which encircles the kc i c Thoseportions of the rods B and G which re embedded in the jawE, may, if desired, be provided ,with interlocking projections L which may, be convenientlyformed by slightly flattening these ends of the rods. T ese portions of the rods will, of course,

7 not be coated, but will be allowed to fuse or said, a .Nnmeybe e pl y d as a Pre r ry rigidly adhereto the cast metal. I I lteferringnow to Fig. 2, it will be obse vedthatthe jawactuating screw bar A has; its,- flattened portion a embedded in a and through which ,a rod N passes. "od may also be formed, of steel and assembled n t emo d in t e relation to he ne b r in hi is n. i ig 2, aftenwhich-the hub, may be cast-thereon. K nobs O also be. preferablycast upon hers ne i n aq we a an preparto. the casting operation, the central portion, of bar may be coated with Shellac to, prevent adhesion in the hub M, whereby .7 a Sl g lever, the. movement of which through the hub will be limited .by theknobs O.

*While lhave described the clamping jaw resal i eva ls i van i e ia cE s s tionar "twill, of course,.be understood that it is, not material to my, invention which of mal @i ea fi t y th er wfwl sa was ayb placed 111 e Apreparatory gt o adjusting the latter in the mold, the nut beingso adjusted that it Will be embeddedin thej aw F when the casting is-iormedi, Where this is done the jaw threads be in part composed of cast metal and in part will comprise the threads I ef .-thenut, unless the screwthreads are filled with, molding sand and cement adjacent to loat e a t ng cr ti9n', in which case the only engagement of the jaw with the screw will be through the medium of the nut threads. The nut, however, not essential to my invention.
